description The invention relates to a method for calculating the pressure water inflow of a kingston-valve-free ballast water tank in heeling based on a three-dimensional model. The method includes the steps ofS1, establishing a net volume model of a kingston-valve-free ballast water tank through three-dimensional modeling software; S2, establishing reference planes, including an average draft height plane,an inclined water plane, a water inflow free surface plane, a free surface highest plane and a free surface lowest plane; S3, establishing control parameters associated with geometric elements, including input constants, an input variable and output quantities; S4, establishing a water inflow model which is obtained by cutting the net volume model of the liquid tank by the water inflow free surface; S5, solving the equation F(H)=P1(H)*(V0-VP(H))-P0*V0=0 by a mathematical method, inputting an obtained equation solution H into the three-dimensional model, and outputting corresponding pressure water inflow geometric para
